PIN DESCRIPTIONS
VCC : Supply voltage.
VSS : Circuit ground.
Port 0 : Port 0 is an 8-bit, open drain, bidirectional I/O
port. As an output port each pin can sink several LS
TTL inputs. Port 0 pins that have 1's written to them
float, and in that state can be used as high-impedance
inputs.
Port 0 is also the multiplexed low-order address and data
bus during accesses to external Program and Data
Memory. In this application it uses strong internal pullups
when emitting 1's, and can source and sink serveral LS
TTL inputs.
Port 1 : Port 1 is an 8-bit bidirectional I/O port with inter-
nal pullups. The port 1 output buffers can drive LS TTL
inputs. Port 1 pins that have 1's written to them are
pulled high by the internal pullups, and in that state can
be used as inputs. As inputs, Port 1 pins that are exter-
nally pulled low will source current (IIL, on the data sheet)
because of the internal pullups.
In additional, Port 1 serves the functions of the following
special features of the MX10C8050X :
Port Pin
Alternate Function
P1.0
T2 (External Count Input to Timer/
Counter 2), Clock-Out
P1.1
T2EX (Timer/Counter 2 Capture/Reload
Trigger and Direction Control)
Port 2 : Port 2 is an 8-bit bidirectional I/O port with inter-
nal pullups. The port 2 output buffers can drive LS TTL
inputs. Port 2 pins that have 1's written to them are
pulled high by the internal pullups, and in that state can
be used as inputs. As inputs, Port 2 pins that are exter-
nally pulled low will source current (IIL, on the data sheet)
because of the internal pullups.
Port 2 emits the high-order address byte during fetches
from external Program Memory and during accesses to
external Data Memory that use 16-bit addresses (MOVX
@DPTR). In this application it uses strong internal
pullups when emitting 1's. During accesses to external
Data Memory that use 8-bit addresses (MOVX @Ri),
Port 2 emits the contents of the P2 Special Function
Register.
Port 3 : Port 3 is an 8-bit bidirectional I/O port with inter-
nal pullups. The port 3 output buffers can drive LS TTL
inputs. Port 3 pins that have 1's written to them are
pulled high by the internal pullups, and in that state can
be used as inputs. As inputs, Port 3 pins that are exter-
nally pulled low will source current (IIL, on the data sheet)
because of the internal pullups.
Port 3 also serves the function of various special fea-
tures of the 8051 Family, as listed below :
Port Pin
Alternate Function
P3.0
RXD (serial input port)
P3.1
TXD (serial output port)
P3.2
INT0 (external interrupt 0)
P3.3
INT1 (external interrupt 1)
P3.4
T0 (Timer 0 external input)
P3.5
T1 (Timer 1 external input)
P3.6
WR (external data memory write sttobe)
P3.7
RD (external data memory read strobe)
